Application Insights supports ASP.NET 5 applications
We released the first preview of Application Insights for the ASP.NET 5 web applications. It allows you to monitor server requests and exceptions for your application, and collect end-user information and browser page performance. You can find the application on NuGet: Application Insights for ASP.NET 5 Web Applications. Please follow this Getting Started Guide to onboard your ASP.NET 5 application to Application Insights.
